I was at a new hire party that our company threw for an incoming group of employees. I did not sit at a table where alcohol was being served, or partake in drinking of any alcohol, although the venue was at a bar (which was reserved solely for this event). I was in the crowd listening to someone speak, and someone asked me to hold their drink momentarily to record. 30 seconds later, they took it back. I was unsure if the drink was alcoholic or not, however I was also somewhat put on the spot and it would’ve made for an awkward situation with my coworker if I said no. Did I commit a sin? What would be the best way to repent for this if I did?
